hodyreva [135]

<u>Answer</u>:

There are a number of lipids that are found in foods and contribute to various functions in the body. Triglycerides are the most common lipid found in food and in the body; they consist of a <u><em>Glycerol</em></u><u> </u>backbone attached to three fatty acids.

Fatty acids are classified based on the degree to which the carbon chain is saturated with <u><em>Hydrogen</em></u>

A fatty acid is <u><em>saturated </em></u>if it contains no carbon-carbon double bonds,   <em><u>polyunsaturated </u></em>if it contains  two or more carbon-carbon double bonds, and<em><u> monounsaturated </u></em>if it has only one carbon-carbon double bond.

The unsaturated fatty acids can exist in one of two structural forms: the <em><u>trans </u></em>form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of that bond.

When hydrogens on an unsaturated fatty acid lie on the same side of the carbon-carbon double bond, a <u><em>cis </em></u>formation exists.

Antibodies are produced when the body is exposed to
erica [24]


Antibodies are produced when the body is exposed to antigens.

During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.

On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.

The antibodies effectively neutralize the antigen and facilitate its destruction.

When the DNA molecule folds, coils and super coils to fit in the cell what structure does it form?
Alexeev081 [22]

Answer:

<h2>A. Chromosome</h2>

Explanation:

In intermediate phase of cell cycle, DNA replication occurs (in S-phase), so in inter phase, DNA become unfolded and in relaxed state and is available for replicating machinery.

When cell enter into prophase, DNA folds, coils and super coils and finally become in condensed form, which can be seen by microscope.

So this compact form of DNA is called as chromosome.

In humans. there are total 46 chromosomes.
